APPARATUS FOR INSERTING FLOATS IN CAKES OF SOAP.

rSPECIFICA'IEION forming part of Letters Patent No. 695,026, dated March 11, i902.

Application liled May 2'7, 1901. Serial No.62,l22. (No model.)

To all whom t may concern.-

Be it known that I, WASHINGTON BERRY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and usefulV Improvements in Apparatus for Locating Inserts in Cakes of Soap, of which the following is a specication.

This invention relates to improvements in apparatus for locating iioats or other inserts in cakes oi' soap, but relates more partielllarly to the location of floats or other inserts in that class of soaps that are first molded into bars and subsequently cut and pressed into cakes, such as transparent soap, and which have such specific gravity as tocause them to sink in water unless artificially lioated.

A primary object of my invention is to so mold the soap as to have within each cake thereof a suitable ioat, causing a displacement greatly exceeding its weight and upon which may be imprinted or otherwise placed any desired design or form of advertisement or to which may be attached a card -or other device carrying any desired design, advertisement, or device intended to beautify the appearance of the cake of soap when the same is ready for market, as well as to permanently display the design, advertisement, or other device Aduring the use of the soap.

Another object is to have the inserts so snpported in the mold that a bar from which a number of cakes of soap are to be out may be cast so as to envelop the inserts and the supports for the inserts be afterwardwithdrawn from the bar, so that when the cakes are formed each cake will have an insert located at the center thereof and without any evidence of the means by which it was supported during the molding operation.

A further object is to have in such an apparatus a detachable support for the inserts, which may be withdrawn therefrom after the bar is cast or molded, so as to leave the inserts within the bar.

A still further object is to have the inserts and their" supports of such character that the inserts may be easily and accurately centered in the mold, properly distanced apart, and maintained in parallel planes during ,the molding operation without the exercise of more than ordinary care or skill and yet in such manner that the supports may be withdrawn from the inserts after the bar is cast or molded without disturbing the positions of the inserts or marring the finish or appearance of the completed cakes.

These and such other objects as may hereinafter appear are attained bythe devices illustrated inthe accompanying drawings, in which- Figure l represents a vertical longitudinal section through an apparatus embodying my invention, showing the same prepared for molding a bar ot' soap and partially filled with soap and also showing one of the iioats partially broken away to indicate the mannerin which it is supported. Fig. 2 is a View similar to Fig. l, but showing the bar of soap molded and partially Withdrawn from the apparatus. line 3 3 of Fig. l looking in the direction in- Fig. 3 is a horizontal section on the dicated by the arrows and showing the ioat partially broken away. Fig. 4 is an enlarged detail in section, showing how` the packing is applied to prevent leakage between the mold and the sliding support; and Fig. 5 is a detail showing the method of vVholdirvlg thin inserts-such as cards, dse-in position. Like letters of reference indicate-the same parts in the several igures of the drawings. Referring by letter to the accompanying drawings, A is a mold of any suitable size and shape. A convenient form, that of a cylindrical tube, is shown inthe drawings.

B is a pin-support separably attached to the mold A, such as by engaging the lugs or guides a, which maybe formed upon the mold A. The support B is provided with openings b, which receive the pins c, which are carried upon the pin-supporting rod C.

I prefer to provide my mold with a separable cap D, which is provided with a conical deiiector E of smaller diameter 'than the internal diameter ofthe cap D. The deiieotor E is supported by the spider e and provides an annular opening within the cap D and around the detlector E. I prefer to have the base of the detleotor of suchsize that soap iowing through the annular opening d will have a tendency to fall to the bottom of the mold without striking any of the inserts F.

To prevent leakage of soap from the mold,

ICO

any suitable packing may be provided between the mold and the pin-support or slide B-such, for instance, as the rubber packing G shown in Fig. 4. The inserts or floats F may be formed either with radial holes or with a peripheral groove of suitable dimensions to receive the ends of the pins c.

My improved mold is used as follows: The pin-support B, being detached from the mold., the pins c, which are attached at one end to the pin-rod C, are inserted through the openings b b in the support B, and the inserts F are mounted upon the outer ends of the pins c by inserting the ends of the pins in the holes or peripheral grooves in the inserts F. This is done in such a manner that the inserts Will be properl7 centered in the mold as Well as properly spaced apart. The support Bis then attached to the mold with the pins c in place and with the floats or inserts F properly mounted thereon. The parts as so assembled appear as shown in Fig. l. As the liquid soap is now poured into the cap D it is deflected by the conical deiiector E and falls along the inner Walls of the mold A to the bottom of the mold and then lls the mold, thereby surrounding Without disturbing the inserts F. As soon as the soap shall have cooled and hardened sufficiently the pin-rod C is drawn outwardly, as shown in Fig. 2, thereby causing the pins to disengage from the inserts F. The support B, together With the pin-rod and pins, may now be removed and the soap forced out of the mold. It Will then be found that this operation has produced abar of soap containingI a number of inserts spaced equally apart and held substantially parallel with each other, so that the bar of soap may be cut into cakes, each cake containing a float in its center. The cakes of soap now being pressed into any desired form, the openings left by the pins c when Withdrawn are closed, and the cakes of soap are completed. Where it is intended to insert cards or other thin inserts, the pins c are provided at their outer ends With slots, Within which such inserts are fitted, as shown in Fig. 5.

Although I have shown a slotted tube, it is obvious that my invention may be embodied in a sectional mold hinged together, which is capable of being broken open to release the soap or to place the inserts in position; but this and other obvious changes are contemplated by my invention and are not a departure from the spirit thereof.

Having thus described my invention, what 1. The combination with a soap-mold, of a separable pin-support arranged upon the exterior of said mold, a pin-rod, and aplurality of insert-supporting pins attached thereto, substantially as described.

2. In a soap-mold, the combination with a mold, of a longitudinal slot therein, a separable'support arranged upon the exterior of said mold and adjacent to said slot, a pin-rod separate from said support, aplurality of pins carried by said rod, and apertures through said support for receiving said pins, substantially as described.

3. In a soap-mold, the combination With a vertical slotted tube, of a sliding support, a plurality of insert-supporting pins carried thereby, and a deflector arranged to deflect the flow of liquid soap away from inserts mounted upon said pins, substantially as described.

4. In a soap-mold, the combination of a mold, a separable support, a pin-rod With a plurality of pins carried by said rod, and a dellector arranged to deflect the flow of liquid soap away from inserts mounted upon said pins, substantially as described.

5. In a soap-mold, the combination With a mold, of means, separable laterally from said mold, carrying a plurality of pins for supporting soap-inserts Within said mold, substantially as described.

6. In a soap-mold, the combination With a mold, of a pin-support arranged upon the outside of said mold, a pin-carryin g rod arranged upon the outside of said pin-support, a plurality of insert-supporting pins carried by said rod,and registering -perforations through said support and through the Wall of said mold, arranged for the passage of said pins, substantially as described.

7. In a soap-mold, the combination With a mold, of a pin-supporting rod arranged on the outside of said mold, and laterally separable therefrom, a plurality of insert-supporting pins carried by said rod, and a plurality of corresponding perforations through the Wall of said mold for the passage into and from said mold of the free ends of said pins, substantially as described.

8. In a soap-mold, the combination with a mold, of a hollow pin-support arranged on the outside of said mold, a pin-carrying rod, a plurality of insert-supporting pins carried by said rod, and a plurality of registering perforations through said pin-support and through the Wall of said mold for the passage of said pins, substantially as described.
